HOW LONG WILL MY CYLINDER LAST FULL OF OXYGEN?

This depends on the amount of O2 that is transferred into the bottle at the time of filling. Most shops only put 1000 to 1500 lbs of O2 into a bottle. The Cylinders are rated for 2200 lbs but you will rarely find someone to fill that much. Based on our experiences, the chart below can be used as a guide for the real world.

D Cylinder (Most Common)

Flow Rate of 1/32 - 100 hrs, Flow Rate of 1/16 - 50 hrs, Flow Rate of 1/8 - 25 hrs

CAN I USE A MEDICAL CYLINDER FOR MY SYSTEM?

A person can do whatever they want but, if the cylinder has a medical grade (standard CGA870 post valve) the common practice is to require a prescription to fill. Since most welding and bait shops do not carry medical grade O2, this should not be an issue. We do not fill or advocate anyone to use these types of valves for recreational Oxygen Systems. We only sell and fill Standard Industrial CGA540 valves.
